parentima: Shallow copy the args_p member of ima_rule_entry.lsm elements (diff)

ima: Use correct type for the args_p member of ima_rule_entry.lsm elements
Make args_p be of the char pointer type rather than have it be a void pointer that gets casted to char pointer when it is used. It is a simple NUL-terminated string as returned by match_strdup().
